to be instituted thereby effecting the reading of such characters orindications, and thus replace reading by a person.

In order to attain this object the arrangement w according to thepresent invention is provided with cells, in which the electricconductivity is varied by radiation. and with comparison devices whichon the arrival of certain rays iniluencing the cells direct or controlthe corresponding op- 15 erations,

The invention can be utilized for controlling any desired machine,however it will be found very useful in connection with oiilce-machines,which heretofo're could be operated only by per- 20 sons who were ableto read. Further the machine may be used for testing and countingsecurities, bank-notes and so forth and for controlling automatons andthe like.

One of the modes of carrying out the present 25 invention is illustrateddiagrammatically by way of example on the accompanying sheet of drawingin which:-

Fig. 1 shows a perspective view of one construction, and

30 Fig. 2 is a detail view.

The embodiment shown in Fig. 1 serves for controlling the countingmechanism of a calculating machine. The record or sheet I, provided withcharacters or the numerals for calculation,

35 is placed on a base or carrier 2 in such a manner, that the number tobe read is dlsposed opposite the lens 3, the record being illuminated bya strong source of light 4. On the other side of the lens 3 a suitabledistance away, is ar- 40 ranged a photo-electric cell 5, in front ofwhich rotat-es a movable device such as a. wheel 6 constituting aportion of a comparison device, provided with stencil-recessescorresponding'to the numerals to 9. The stencil-recesses are of such 45a size and are shaped according to the numerals and are distanced insuch a manner from the lens 3 that for instance the` image of thenumeral l exactly coincides with the stencil-recess as soon as thelatter is dlsposed atlthe cor- 50 responding place. A contact wheel 'I,provided with nine contactknives 8 and supplied with current by way of abrush 9, is connected With the wheel 6. A`contact-spring III is arrangedopposite the contact wheel in such a manner,

55 that the knives 8 establish electric connection during the rotationof the said contact A wire of an Operating circuit leads fromv thecontact spring loto a conta'oi-magnet ,|2 which on being charged withcurrent attracte the armature il and by way of a link ll forces a pawlIB against the action of a spring II into a toothed feed-wheel |1 andfeeds forward the latter for the extent of a tooth. A number-wheel ornumber representing or manifesting wheel ll is connected with thefeed-wheel Il and accordlnsly 10 is fed forward also the extent of oneplace. In the circuit of the photo-electric cell I are included a lowfrequency transfonner 88 and a relay-magnet IS, which controls thecurrent SUP- ply of the brush 9., During the rotation of the wheel 6,rays of light will periodically pass to the cell l by way of thesuccessive stencll-recesses of the wheel 8. The cell 5 is subiected tofull light if a blank place'of the sheet I is dlsposed opposite the lens8` 'However a numeral, for instance the numeral 1, does not completelyfill the other stencil recesses as shown in Fig. 2 by way of example ofthe stencil-recess corresponding to the Figure 2. Therefore light of thewhite writing sheet still passes to the cell I. l However a minimum ofillumination of the cell 5 will take place, as soon as thestencii-recess corresponding to the numeral to be read is disposed infront of the cell. The relay IO in the i' control eircuit 38 is adiustedto' this Ailluminatlen-minimum and allows the withdrawal of. itsarmature 2| by means of the action of the spring 20. In this way thecontact member 22 is released and thus the current-supply to the brush 9is interrupted. Supposing the numeral 1 is to be read off, acontact-knife 8 would already have passed the contact-spring Ill at thetime of the release of the relay-armature 2| and the figurewheel |8would have been fed forward for a unit by the generated current. The'eight following 40 'contact-knives 8 would remain inoperative, be-

cause the current-supply tov the brush 8 is interrupted. Supposing thenumeral 3 is to be ,read .011, three contact-knives would have become'operative the flgure-wheel would have been fed forward for three units.and so forth.

Two camsV 23 and 2| return ,the parts 2| and 22 into the initialposition after each revolution of the wheel 8. i The wheel 0 with thenumerals or other characters thereon, constitutes a movable searchmember or character-bearing comparison device in the path of the rays ofradiant energy. With said device move the wheel 'I and itsv contactknives or blades 8, said parts 1, 8 constituting 56 a control meansadapted to open or close. at the contact spring lt, a sap in theOperating circuit il which includes the work device or magnet i and alsohas another gap which is open or closed bythe relay armatura Ii, thelatter thus constituting another control means or control device for theOperating circuit ii, which second control means is under the control'of the photoelectric cell or other ray-'Sensitive device The magnet |2through its armatura it and the parts connected therewith, controlsmanifesting means constituted by the wheel ll. This wheel moves in stepwith the wheel 'i as long as the character on the wheel 'I struck by theradiant energy does not correspond to the character on the record, butwhen the two characters do correspond, the manifesting wheel i! stopsowing to the interruption of the Operating circuit at 2|.

No separate source of current is required in the circuit of thephoto-electric cell when the latter is of the type that generatesanelectric current when exposed to light. When using a photo-electric cellof the other type. which does not generate a current but simply variesin resistance under the influence of variations ofv light, I would ofcourse include a battery or other suitable Sourcev of current in saidcircuit.
